Three new and one known species of the genus Aporcelaimellus with simple uterus and typical caudal region, mainly col-lected in natural areas of southeastern Iberian Peninsula, are studied, including descriptions, measurements, line illustrations and LM pictures. Aporcelaimellus baeticus sp. n. is characterized by a body length of 1.96-2.95 mm, lip region offset by constriction and 17-20 μm bro...

The predation of a luminescence-marked strain of Pseudomonas fluorescens by the soil ciliate Colpoda steinii was studied in soil microcosms. Bacterial cells were introduced in either small (neck diameter, <6 (mu)m) or intermediate-sized (neck diameter, 6 to 30 (mu)m) pores in the soil by inoculation at appropriate matric potentials, and ciliates were introduced into large pores (neck diameter, ...

BACKGROUND AND PURPOSE Our goal was to characterize the geometry of simple-lobed cerebral aneurysms and to find the absolute size of these lesions from angiographic tracings. METHODS Measurements of angiographic neck width (N), dome height (H), dome diameter (D), and semi-axis height (S) were obtained from tracings of 87 simple-lobed lesions located at the basilar bifurcation (BB), middle cer...

OBJECTIVE The objective of this study was to evaluate gender differences in the selection, procedure, and outcome of endovascular abdominal aortic aneurysm repair (EVAR). PATIENTS Between October 1996 and January 2001, 378 patients were evaluated for EVAR and 189 patients underwent EVAR with the Medtronic AneuRx stent graft at a single center. RESULTS Women constituted 17% of patients consi...

BACKGROUND AND PURPOSE Our purpose was to describe the association between narrowing of the internal carotid artery (ICA) and retropharyngeal abscess in children. METHODS Neck CT scans from 13 consecutive children with suppurative retropharyngeal lymphadenitis and abscess were evaluated retrospectively for asymmetric ICA diameters at the level of the abscess. Clinical status at the time of il...

There is increasing evidence that proximal femoral geometry has an important role in the aetiology of hip fractures. We performed a simple radiological study to investigate the relationship between proximal femoral geometry and intracapsular and extracapsular fractures of the proximal femur. Measurements of proximal femoral geometry were made on pelvic radiographs on the contralateral hip of 50...

An 85-year-old man was found to have a 9 cm diameter true aneurysm of an obtuse marginal saphenous vein graft. The graft was fed by a relatively narrow neck from the proximal remnant of the obtuse marginal graft 10 years after prior coronary artery bypass graft surgery. An Amplatzer vascular plug was used successfully to occlude the neck of the aneurysm. Follow-up CT scan 1 month afterward demo...

PURPOSE The aim of this study was to assess vascular changes and blood flow abnormalities in the common carotid arteries of patients with head and neck cancers after external radiotherapy, using color Doppler ultrasonography. METHODS We studied 24 patients treated with external radiotherapy for various head and neck cancers. In order to study the acute effects of irradiation on common carotid...

OBJECTIVE Provide reference basis for the clinical implant restoration to select implant diameter through measuring each data of 7 teeth in the dental neck of bilateral upper and lower jaws of the young volunteers with normal dentition. METHODS Select 30 healthy young volunteers with complete dentition but no malocclusion, take cone beam CT (CBCT), measure the mesiodistal and buccolingual dis...
